Group-based interventions in health care have demonstrated a positive influence on patient outcomes by strengthening patient-healthcare professional relationships and providing an avenue for patient empowerment through shared experiences and belongingness. Groups have been shown to enhance social and psychological support, improve self-management behaviors, and encourage peer-support. However group settings also present challenges, such as discomforts in sharing within a group context and managing diverse group dynamics. We outline the efficacy and dynamics of group-based activities in health care settings. This includes key behavioral components of groups, such as creating a safe, supportive, and cohesive environment in group activities where confidentiality is paramount. By recognizing principles for group and moderator behaviors, individuals are more likely to maximize the potential of these interventions.
